Title: Powder paint stenciling on a powder paint substrate
Inventor: RODELY BRIAN
IPC: B05D1/32
Filed: 1997-11-14
Granted: 2004-04-13
Abstract: A novel method of marking appliances is described.      The method comprises coating an appliance or other substrate capable of producing an electrostatic charge with a first powder paint layer. This first layer is then either cured or a second powder paint layer is applied immediately thereafter in the desired design or lettering. The layered substrate is then allowed to cure. The invention presents the advantages of eliminating the need of a volatile ink and the capability of being performed in one step.

Abstract: An electrical testing device for determining the continuity between ground terminals of an electrical power cord and determining the electrical grounding of an electrical power tool.   The electrical testing device can also be configured to determine the proper polarity on each of the hot, negative, and ground cord wires of an electrical power extension cord.   The electrical  testing device  includes  a plastic  case housing one or more batteries which supply power to a test  button and  the  ground  terminal  of  a  female receptacle installed in the case.  The top surface of the case includes a female receptacle, a test button, and a ground light.  The top surface may also include a  male plug  and  an  additional  female  receptacle installed in the case.   On the side of the case is an extending metal contact element.  The test button is a single pole momentary contact test button.   When this test button is actuated it closes the test button contacts  thus  completing  a  circuit  which  will illuminate the light if the light and the battery are good.

Title: Water wheel with cylindrical blades
Inventor: BERGSTEIN FRANK D
IPC: F03B1/00
Filed: 1998-09-03
Granted: 2000-06-06
Abstract: An improved liquid rotor device is provided having a cylindrically-shaped hub, which is supported by a horizontal shaft, and having several curved blades which are attached to the outer portions of the rotating hub. The horizontal shaft preferably rotates with the hub so that it can mechanically drive a device such as an electrical generator. The multiple blades mounted to the exterior surface of the hub are curved such that the longitudinal axis of each blade is parallel to the axis of rotation (i.e., the horizontal shaft). Each blade is arcuate in shape and preferably comprises a portion of the cylindrical wall of a hollow cylinder. In one embodiment of the present invention, the rotating hub and blades sub-assembly is surrounded by a hollow cylindrical housing that is entirely submerged in a liquid, such as water. The surrounding hollow cylindrical housing has an inlet to receive the liquid into the area of the rotating blades and an outlet through which the liquid is discharged. The inlet preferably is in communication with the discharge of a constricting chamber that has a large opening area and a small discharge area, such as a portion of a venturi. By use of this chamber, the velocity of the liquid is increased as it approaches the inlet. In a second embodiment, the rotating hub and blades sub-assembly is made to be buoyant so that the centerline of the rotating hub will be approximately at the surface of the liquid, so that the liquid rotor will essentially float along the surface of, for example, a stream, river or canal. The curved blades are directly exposed to themoving liquid, as well as to the wind of the gaseous air above the surface of the liquid. If the direction of the liquid current is substantially the same as the wind direction, then the wind will tend to inhibit the rotation of the blades and hub sub-assembly. In order to provide a reduced cross-sectional area against which the wind can act, the curved blades are hinged at the surface of the cylindrical hub, so that the wind will have less surface area to act against.

Abstract: The Highly Structured Rosette Antenna Array Data Communications System is a high capacity wireless network in which data is communicated from and to remotely located subscribers. The system uses cells that are comprised of a multiplicity of oblong microcells arranged in a circle, giving the cell a rosette-like pattern. like frequency channels are assigned to every N"' microcell, where N is the number of distinctly different frequency channels. The sum of the distinctly different channels is the total bandwidth assigned to the rosette. Typically, if M is equal to the total number of microcells in the rosette, then M/N is equal to the number of like-frequency microcells in the rosette.
